Abstract

A colorimetric receptor L was prepared. Receptor L can selectively sense F^- based on distinct color changes among a series of ions. It can selectively sense F^- through an intramolecular hydrogen bond interaction. A Job plot indicated a 1:1 complexation stoichiometry between receptor L and F^- . The association constant for L-F^- in CH₃ CN was determined as 9.70 × 10⁴ M^-1 using a Stern-Volmer plot.

Keywords: colorimetric; fluoride ion; sensor.
